Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a use-after-free error in the iwlwifi module of the Linux kernel. When no firmware is present or all firmware files fail to parse, the device release driver() function is called, leading to the removal of the 'drv' struct. However, the new code still attempts to access the freed struct, causing an error. Setting 'failure=false' can avoid this access. The vulnerability may impact the confidentiality, integrity, and availability of protected information.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
